As that guy mentioned, these type of events, it's more worth it to sell the bundles rather than open them yourself.

Indeed, and best is to sell during the first 1-2 days, after that the prices drop a lot. But it gave quite a nice profit, so I approve of the event. It's up to everyone to decide how to play the event, either sell or gamble with opening them. For me they break a lot after +7, so I decided it's not worth it.

So, today on the final day i did a Mass opening of all the +1 Matryoshka i collected (on different Server and Accounts), and here is the result (not counting the "31" i did on the first day, and any Spinel Shards).

I'm just wondering, are the Luminiel Weapons that come from that weapon chest actually useful? The stats seem really high, but it's only level 65... so err.. keep or try to sell it?

Depends on your needs actually.
I think Luminiel Weapons do sell for 1kkk+ on many Servers usually and are in demand because of their stats.
But if you need them then don't sell (mostly this is dependent on your class and how much PvP you do or like doing, as they are mainly in demand for PvP).

With next week's maintenance on the 9th of August, we will remove all left over event bundles from the Blue Sheep and Matryoshka events. This includes all Martryoshkas themselves, as well as the reward bundles for enchanting them and the reward bundles for feeding your pets with Chili Chocolate. Please make sure you've opened all of them until this point!

All the best,
The AION Team

Seriously, why are you doing this.
You are destroying the income source of many players like this you know. Some try to sell those stuff at a later date, when the price are a bit high to make a profit, as the price of other stuff is really high. But now you have started doing these things.

I am sorry but the reason that they make this is because after when you will open them will drop good stuff and you will get to rich this think have start with the box of scrolls that in the event time drop 5 and after event pass you take 50 .

this think have start with the box of scrolls that in the event time drop 5 and after event pass you take 50 .

Do u mean the "Box of Blessing", that we got from the Heal Camp Event?
But i have quite many unopened ones, and they give me only 10 scrolls (of any type i pick) even now, just like how it was during the last time we had that Event. Before that it was 50 or 30 (don't exactly remember) each.

Well they fix it , it was exactly like a bug and from then they begin to remove everything what is from the event when the time pass maybe is good but maybe not because maybe I wanna keep one of them to remind me about this event , maybe I collect thinks in aion

This seems unclear as to what bundles will be removed. If you got a weapon chest, a manastone bundle, stigma bundle? I am very guilty of not opening things until i know what character needs.. or to save space in inventory.
